Aramex: a delivery disaster

I ordered over R2000 of goods from a clothing website called Shein. Aramex was meant to deliver my order, and it was delivered to someone on the 12th of August 2020. Aramex made a mistake, and delivered my package to the wrong house/ person. I received a notification from Shein informing me that my package was delivered, however it was not delivered to me. I tried calling Aramex multiple times and only two weeks of me calling did someone actually help me, a lady working for Aramex by the name of Tirusha. Tirusha sent the driver back to the house he delivered the parcel to retrieve it. He only retrieved two of my 7 items and said that the person whom he collected it from says that they did not know where the other items were. He came back once more, with one more item. I phoned and emailed Tirusha multiple times after that to see how I would be compensated for my missing items- she did not answer any of my calls or emails. I phoned Aramex directly after that, around 6 times- every time I’ve called, someone said that they would get back to me in no less than an hour however no one got back to me. I am extremely tired of making calls (wasting my time, energy and airtime) only to be ignored and forgotten about by a company who is responsible of misplaced my package. I understand that it was a mistake on behalf of Aramex however they have not been helpful at all in assisting me or trying to make amends for their mistakes. I have been more than understanding and I am so disappointed with their poor service delivery.
